shape retention
1.The process conditions are optimized, that is, protease 4%(owf), pH value 8, temperature 50℃ and time 45min. After treatment, the fric tion coefficient of the surface and the rigidity of hairiness of the fabric obvi ously decline, and the exterior of fabric becomes more bright and clean, meanwhi le, the wearability, the crease resistance and shape retention are raised.
